  1. Wonderful! Except For Blue Paint.

    Posted by G. Thomas on 20th Jun 2016

    I ordered two of these 20oz water bottles through Mass Drop and although they performed as claimed the bottle with the smooth blue finish already has paint coming off and the ECO Vessel logo has all but vanished. The other bottle is orange in color and reminds me of a Duracoat type finish and is holding up much better than the blue bottle. When I ordered my bottles I thought that both would be the same Duracoat type finish, and it looks as though according to the pictures that they now all ship with that type of finish.

    Overall I am extremely happy with my purchase, placing ice and water inside lasted well over 24 hours, and all of the other parents were jealous and asking me where I purchased my bottles from, and of course I directed them to this site.

    I just wish that my blue bottle had the same finish as the orange one has.

  2. Love the new size

    Posted by Jessica E on 13th Mar 2015

    The size of the new Boulder is the only reason I am giving them 4 stars. I love how much smaller the new Boulder is and that it actually fits in my cup holder in my car but the only downfall is it does not keep Ice as long as the older style. We also have the older style and that keeps ice for days as for the new Boulder it does not even make it throughout the day.
